Princeton Reverb Tranny originality

I'm looking for some feedback on a Tranny that was called into question of its originality.

I have a 67' Blackface PR and Here is the pic. It's definitely an old piece but I have seen both that are of this type and others with the metallic cover on them as well. I was hoping someone might have an idea.

Also there was a BF PR on evilbay that just sold with a similar interior to my own. It has the same type speaker and everything. So I was thinking that potentially there was a run from 66 - 67 where different trannys might have been used.

I noticed that this tranny looked weird when you posted the amp for sale a while back. Is it painted black? (if so, that's weird thing #1) Does it have a manufacturer/date code? (if not, that's weird thing #2).

p.s. the tranny in my '67 PR is silver metallic, with a manufacturer/date code. Also, it has plastic covered wires coming out of it, not cloth covered wires...

i dont know that its painted black but its definitely been in the amp for a long time with the rust and age and there doesnt seem to be any new solder marks or anything that would suggest its not original

Because I've seen many dozens of Princeton Reverb transformers and they all had the shrouded Schumacher OT. I guess I shouldn't say "definitely" as I wasn't there when this transformer was installed, but personally I wouldn't believe it was original.

Maybe the OP could post a pic of the chassis inside? The look of the solder joints on the OT leads, as well as their routing, will likely tell the story.

- seen it more than once
- EIA date codes that are congruent with other EIA date codes on the amp (s)
- originality of the solder joints
- "masking" on the chassis where the OT mounting ears protected the chassis underneath from 40+ years of environmental dirt / oxidation / nicotine / etc.
